THE INFLUENCE OF THE HEART-BEAT ON THE FLOW OF BLOOD THROUGH THE WAL,LS OF THE HEART.l

چکیده
I N 1689 J. Baptkta Scaramucci2 published two hypotheses which have played a great part in the history of the physiology of the heart: the first, that the deeper coronary vessels are squeezed empty by the contraction of the muscle fibres which surround them; and the secondi, that the coronary vessels are refilled from the aorta during the diastole of the heart. In 1707, Stroem 3 added to these the hypothesis1 that thlz coronary vessels are filled in diastole because their mouths are closed in systole by the semilunar valves. Thus, almost at the outset, the penetrating conception of Scaramucci was linked with an obstinate and overshadowing error, destined to be a source of controversy for nearly two hundred years.* Thebesius,

A Mathematical Model for Blood Flow Through Narrow Vessels with Mild-Stenosis (RESEARCH NOTE)
In this paper we examine the effect of mild stenosis on blood flow, in an irregular axisymmetric artery with oscillating pressure gradient. The Herschel-Bulkley fluid model has been utilized for this study. The combined influence of an asymmetric shape and surface irregularities of constriction has been explored in this computational study. An extensive quantitative analysis has been performed ...
متن کاملMathematical modeling of blood flow in a stenosed artery under MHD effect through porous medium
In this investigation, a mathematical model for studying oscillatory flow of blood in a stenosed artery under the influence of transverse magnetic field through porous medium has been developed. The equations of motion of blood flow are solved analytically. The analytical expressions for axial velocity, volumetric flow rate, pressure gradient, resistance to blood flow and shear stress have been...
متن کاملA Numerical Analysis for the Effect of Slip Velocity and Stenosis Shape on Non-Newtonian Flow of Blood (TECHNICAL NOTE)
The aim of this paper is to study the effect of slip velocity and shape of stenosis on non-Newtonian flow of blood through a stenosed arterial segment. Blood is modeled as Bingham-Plastic fluid in a uniform circular tube with a radially non-symmetric stenosis. The problem is investigated by a joint effort of analytical and numerical techniques. The influence of stenosis shape parameter, slip ve...
متن کاملThe Role of Nitric Oxide and Prostaglandins in the Effect of Adenosine on Contractility, Heart Rate and Coronary Blood Flow in Guinea Pig Isolated Heart
It is a well-established fact that adenosine and its receptor subtypes (A 1 and A ) are involved in changes of contractility, heart rate and coronary blood flow (CBF) under different circumstances. This study was conducted to evaluate the role of nitric oxide and prostaglandins in development of these changes. For this purpose, Nitro-L-Arginine methyl ester (L-NAME), and indomethacin as inhibit...
متن کاملStudies on thiopentone and midazolam hemodynamic response during induction of anesthesia in patients with coronary artery disease
Background: Induction of anesthesia in patients that undergo cardiac surgery has more risk than others, because of specific cardiovascular effects of the anesthetic drugs and the preoperative state of these patients, so the hemodynamic stability is very important in these patients. It seems that midazolam have less cardiovascular side effects than thiopentone. In this study, the effects of mid...
